a. A leaf fragment exhibiting yellow striation symptoms from a Saccharum officinarum plant (variety NG28-020) found to be infected by sugar cane striate virus. I: Upper leaf surface, II: Lower leaf surface. b. A maximum likelihood phylogenetic tree constructed from the full genome sequences of six SCStV isolates that were determined in this study, together with a SCStV isolate from China (inferred using GTR + I + G substitution model which was selected as the best fitting model using jModelTest [19]. Support for branches was tested using an approximate likelihood ratio test (aLRT). Branches with less than 80% support have been collapsed. c. Pairwise identity matrix of the SCStV genome sequences
